Subject: f2fs: Use a folio in f2fs_is_cp_guaranteed()
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=a824388d911927b2a82bf7dcfd7cef6ee45c8b43;p=users%2Fwilly%2Fxarray.git

f2fs: Use a folio in f2fs_is_cp_guaranteed()

Convert the passed page to a folio and use it throughout.  Removes
a use of fscrypt_is_bounce_page(), which we're trying to remove.
